IMPROVEMENT IN VEHICLE-SPRINGS.

Specification formingpart of Letters Patent No, 150,685, dated May 12,1874; application filed February 7, 1874.

To all whom it may concern:

7 Be it known that I, JAGOB H. GOULD, of Rutland, in the county of Meigsand State of Ohio, have invented a new and Improved Oarriage-Spring, ofwhich the following is a specification In. the accompanying drawing,Figure 1 represents a sectional end view of my improvedcarriages1')ring; and Fig. 2, a horizontal longitudinal section of thesame on the line 0 c, Fig. 1. r

Similar letters of reference indicate corresponding parts.

The object of my invention is to produce a spring for vehicles of allkinds which gives great resistance and uniform elasticity to the weightpressing thereon, with less material.

'andfriction, being also less expensive in its manufacture, and, 011account of the equalized strain, more durable and satisfactory. Myinvention consists of a series of spring plates or leaves, which aretapering from the center toward the ends, and of equal thickness alongThe leaves A are made of steel plates, of equal length and thicknessthroughout, either of symmetrical halves, or extending the full lengthfrom socket to socket. They are tapering in width from the central partto the end, and flat, without corrugations, to produce an equal degreeof elasticity throughout their full length, and prevent thereby breakagecaused by unequal strain on any part thereof. Each leaf A is attached,separately from the other, to the central blocks B and sockets, and atsuch distance apart that they do not come in contact with each other,however great the pressure exerted on them.

In case half leaves or plates are used, the central blocks B arerecessed at the ends, for

taking up the sam e, and bound firmly together by vertical cross-boltsa.

If full plates are used, separate blocks are interposed between, forretaining the requlred distance of the plates.

The outer ends of the leaves A rest on sep arate pins 1), which arelubricated by an oiled wick, or similar substance, placed vertically inthe sockets back of the pins, as shown 111 Fig. 1. The friction of thesprings and wearin g out of those parts are thereby materially reduced.

For the purpose of adjusting the springpower to the weight to besupported, the intermediate or middle plates may be made detachable, andinserted or taken out, as required. The inner ends are, therefore,provided with slots (1, as shown in Fig. 2, wh ch slide onto theconnecting-bolts a, resting with the outer ends loosely upon theirsocket-pins.

Repairs can easily be made, as any injured plate may be replaced withoutdispensing with the rest.

The action of the spring is uniform throughout its full length,producing thereby more agreeable movements and greater com-fort to theoccupant of the vehicle.

Having thus described my invention, I clann as new and desire to secureby Letters Patent' l. The vehicle-spring composed of separate taperingleaves A, central blocks B, and lubrieating-sockets O, all combined insuch manner that the plates are constantly retained at certain distancefrom each other, as and for the purpose described;

- 2. The detachable spring-plates A, with side slot d, in combinationwith the cross-bolts a, supporting-blocks B, and the lubricatedsocket-pins, as and for the purpose described.
